m Be/(132 Patented Nov. 22, 1932 JACOB A. BERDAN, OF PORT HURON,MICHIGAN WINDSHIELD WIPER ATTACHMENT Application filed February 16,1982. Serial No. 593,843.

This invention relates to attachments for windshield wipers for motorvehicles and pertains particularly to an attachment which is designed toapply frost preventing devices to the windshield.

The primary object of the present invention is to provide a windshieldwiper attachment for applying anti-freeze solutions to the windshield,which is designed to be readily mounted upon the regular wiper to becarried thereby and to operate upon the windshield in place thereof.

Another object of the invention is to provide an attachment of the abovedescribed character which may be readily applied to the windshield wiperand held in operative engagement therewith without the use of screws,bolts or other removable securing elements.

Other objects and advantages of the invention will become apparent asthe description of the same proceeds and the invention will be bestunderstood from a consideration of the following detailed descriptiontaken in connection with the accompanying drawing forming part of thisspecification, with the understanding, however, that the invention isnot confined to any strict conformity with the showing of the drawingbut may be changed or modified so long as such changes or modificationsmark no material departure from the salient features of the invention asexpressed in the appended claims.

In the drawing i Figure 1 is a view in side elevation of the attachmentembodying the present invention showing the same applied to a windshieldwiper, a portion of the attachment being broken away for theillustration of a portion of the interior thereof;

Figure 2 is a transverse sectional view taken on the line 2-2 of Figure1 Figure 3 is a plan view of the lower end of the attachment.

Referring now more particularly to the drawing wherein like numerals ofreference indicate corresponding parts throughout the several views, thenumeral 1 indicates generally a windshield wiper of the usualconventional type which is supported in operative position by the rod 2through the medium of a clevis 3 which is carried upon the lower end ofthe rod 2 and which receives the back of the wiper and which is attachedthereto in the manner shown, by a bolt or screw 4.

The attachment embodying the present invention comprises a single unitwhich is inicated as a whole'by the numeral 5 and which consists of anelongated tubular receptacle 6 having an inlet opening 7 at its upperend which is normally closed by a plug 8. A wall of this receptacle 6 isprovided with a longitudinally extending outlet 9 which is'in the formof a very narrow slit and this slit opens into a channel 10 which isformed integral with the receptacle wall and which extends throughoutthe length of the receptacle and has the side wall portion 11 and theend walls 12; 7

Firmly secured in the channel 10 and extending throughout the lengththereof and furtherprojecting a substantial distance forwardly from theopen side thereof is a felt wiper 13, the inner edge of which covers theslit 9 which opens into the receptacle 6. At the side of the receptacleopposite the channel 10 there is formed integral therewith a secondchannel which is indicated generally by the numeral 14 and which opensin the opposite direction from the channel 10 and has the side walls 15and the top end wall 16, the lower end of the channel 14 is open.Intermediate its ends the side walls of the channel 14 are cut out asindicated at 16 and for the purpose herein described. Extending acrossthe channel 14 at points upon either side of the transverse centerthereof are loops 17 which maintain the wiper 1 in place in the secondmentioned channel 14 as is also herein described.

Inthe use of the presentwindshield wiper attachment the same is appliedto ormounted directly on the wiper but without disconnecting thesamefrom its supporting arm or in any way altering the regular wiperstructure, by holding the wiper element 1 away from the windshield andthen inserting the lower end thereof into the channel 14 above the loop17 which is nearest the open end of the channel. The device .5 is

then moved vertically along the wiper 1 until the upper loop 17 is in aposition above the upper end of the wiper 1 whereupon the upper end ofthis wiper is then moved into 5 position in the channel 14 and thedevice 5 allowed to slide back down on the wiper 1 intwthoi illustratedin. Figure 1. Withthe inal windshield wiper the felt portion 13 willposition against the windshield glass and will have transferred theretothe'glycerine-or other li uid which the receptacle 6v contains.

It wi l, of course, be readily understood that the anti-freeze solutionor any other suitable liquid or substance which will pre- Who 'onofimoisture on'the'velnelevwindshield, such for: examplevas glywilhpass-through therslotr 9: of the receptaclefiiinto the channel10'an-disa'turltefthe feltrxwiper 13'from which,.as previtps lystated;.it will be tramsferred'sto the stflfm 0f the; windshield vglass.
